Probably Jeff was being polite, giving you the benefit of the doubt,
allowing you to remain innocent-until-proven-guilty, etc. The fact is,
there are very few good reasons to use symrefs -- exporting symbols is
the only one I can think of -- and if you have a good reason, you'll need
to give us some more information.

It's not that there's "NEVER" a good reason to use symbolic references.
It's just that the code you posted doesn't have one. :-)

Use a hash of array references. Instead of this:
@$name = (1,2,3); # gack! what if $name is "_" or "INC"?
use this.
$hash{$name} = [1,2,3];

Unless you think they do filename globbing, that code isn't working the
way you think it works.
